Specification of Letters Patent. P t ted Sept. 13, 1921.

Application filed February 17, 1920. Serial no. 359,339.

T 0 all whom it may concern:

Be it known that we, WILLIAM F. ULLMAN and WILLIAM C. HILLsINoER, citizens of the United States, residing at Syracuse, in the county of Onondaga and State of New York,

have invented'new and useful Improvements in Angle-Cooks; and we do hereby declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form part of this specification.

Like figures of reference refer to lik parts. 1

This invention relates to angle cocks. 7 One object of this invention is to provide an angle cock of such a construction as will, upon a slight turning of the handle from a shut-off position, cause a communication between the hose side of the cock and the atmosphere, to bring about a reduction of pressure in the train line on the car, directly connected with the cock, which reduction of pressure will cause the setting of the air brakes in the well known manner.

A further object of this invention is to provide an angle cockof such a construction as will permit a gradual increase in leakage of air from the interior of the cock, as the handle is turned.

With these and other objects our invention consists in certain construction which is illustrated in the drawings, is hereinafter clescribed, and what we claim is. set forth.

In the drawings,

Figure 1 is a side elevation of an ordinary angle cock, showing our improvement embodied therein; v

Fig. 2 is a top plan section of the angle cock shown in Fig. 1,'taken on the line X-X of Fig. 1'. V

Fig. 4 is a section taken on the line Y-Y of'Fig. 3.

Fig. 5 is an elevation of the hollow plug. a Fig.6 is a diagrammatic section of the plug and bushing of the angle cock casing, taken on the line A of Fig. 1, showing a certain position of the plug relative to the ports in the casing. I i

Fig. 7 is a diagrammatic section of the plug and bushing of the angle cock casing taken on theline B of Fig. 1, showing another position of the plug relative to the ports in the casing.

Fig. 8 is a diagrammatic section of the plug and bushing of the angle cock casing taken on the line C, showing the position of the plug relat ve to the ports in the casing,

vwith one of the three ports entirely closed off, :and full communication established through the side port in the casing.

. In the figures, is shown the angle cock casing 1, with a pipe receiving end 2, and a hose receiving end 3, connected by the channel 4, which is restricted at the vertical ports 5 and 6 through the bushin 7, which is fixed within the casing 1. plug 8 fits in the ordinary way within the bushing 7 and is held in by the nut 8 The plug 8 has a square extension '9, upon which is a projection 10, fitting into the member 11, which is pivoted at 12, to the handle wrench 13 in, the usual way, with theprojection 10 positioned toward the hose end of the angle cock. The member 11, is pinned to the extension 9. Integral with and depending from the upper art of the member 11, is a lip stop 11*.

assing through one of the side walls of the casing 1, and the bushing 7 is a series of four holes, 14, 15, 16 and 17, which open into a pocket 18 on the outside of the casing 1, which pocket is open below and may, for purposes of construction, be made separable from the casing 1. These holes vary in size, the smallest being at the top, and the line of their centers being angular and tilted at the top toward the hose end of the angle cook. The plug 8 has two vertical ports 19 and 20 diametrically opposed to one another, which register with the respective ports 5 and 6,

when the angle cock is full open for. communication through the chamber 8". Through one side of the plug 8 is theport 21, having 1 and 2, having the ports '5 and Get the cas r OFFICE. I

ing bushing 7 register with the ports 19 and 20 of the plug 8, establishing full communication between connecting parts of the train line through thisangle cock, having the at mosphere ports 14:, 15, 16 and 17 closed off by a blank portion of the plug8. Assume now, that the handle 13 is partially turned counter-clockwise, after being raised ,to release the interference of the lug 1 on the casing 1, with the lug 13 on thehandle 13,-

so that the relative position of the ports is as shown in Fig. 6, where the port 19 of the plug 8 is just beginning to eclipse the'small hole 17, permitting a leak to atmosphere, and the port 21 is opening onto the port 5, while at the same time the port 20 is leaving the port 6.; Such a partial turn of the angle cock handle 13 will throw both connections of the 'train' line, communicating with the casing 1, into communication with the at mosphere through the hole 17 and if left so, will reduce the pressure of the train line at this point sufficiently to set the brakes, providing the pump supply, which maintains the air pressure within the 'pipe,,is not sufficient to overcome the reduction of pressure caused by such aleak. A further turning of the handle 13, in a counter-clockwise' direction, will bring the hole 15 in open registration with the port 19, and the port ,6'will be shutoff entirely on account of the port 20 passing beyond registration. with the port 6. The port 21 will open more ,in communication with the port 5, and the hose side of the angle cock will lose its pressure through the holes 15. and 17, andthe brakes will be set on the car directly connected with the hose'side of the angle cock. The position shown in Fig, 8 represents nearly a one-fourth turn of the handle 13, from the full open position, establishing full communication between the port 19 and fall of the holes 14,15, 16 and 17. The angular portion 21 in the upper part of the slot 21, continues the communication between the port 5 and the chamber. 8", after the lower part of the slot 21 has passed out of registration with the port 5, should the handle 13 be turned sufficiently for such a gradation of airflow from thehose side of the 'angle' cock to the chamber 8 and thence to atmospherethrough the holes 14,15, 16 and 17. L

By'havingtheholesl l,.15, 16 and 17 reduced in size from bottom to top and having 1 the line thereof turned forward, the commu- 'nication made with the atmosphere, through the side of the valve is graduated. At the same time by having the portion '21 of the slot 21 ofthe lug 8, inclined to the rear, a

the smaller holes in the upper part of the angle cock casing, communicating with the atmosphere.

It will be observed that such a construction is cheaply made and effects a practical gradation in ways of effecting a reduction in the train line pressure, when the angle cock handle 13 is partially turned through accident or otherwise, and if through accident, then the brakes will automatically become set on the train or at least one part thereof, giving the engineer definite warning as a signal that something has gone wrong, giving him the opportunity to fully stop his train for investigation, to right the difiiculty in the system, before proceeding, and thus avoid such accidents as are'so commonly due to the accidental turning of the angle cock handle.

Having described 8 our claim I g 1. In an angle cock for train lines, including the usual casing and handle, a plug havinvention, we
